Conclusion: The hypothesis was correct. The crysals sunk in the cold water but rose in the hot water.

1. Explain what causes convection currents.

Currents are a flow of water, air, or any liquid (or gas). Convection currents are circular currents or movement within a liquid (or gas) due to different densities of the hotter and cooler parts. Hot liquids are less dense than cold and will rise. In the earth’s deep mantle and outer core, the magma that is closer to the exteremely hot inner core rises because it’s less dense and then pushes the cooler magma that is further from the intense heat down. When the cooler magma is pushed down, it is heated more and rises. The somewhat less hot magma is more dense and so sinks. This motion is convection currents and is what causes the plates to move that are riding on the surface of all of this.

2. Identify the direction of a cold current

Col currents fall becuase hot air rises whereas cold air falls.

1. Explain how this activity relates to the spreading at the mid ocean ridges.

Plates are moving very fast. A weak fault line causes a huge valley to form and magma fills it. The magma cools and solidifies. Old rocks get pushed out the way by new ones.

2. Identify what in your model represents each of the following:

a) Ocean floor or plate- the tables

b) the water-The paper

c) The lava flow-coloured strips

d) gravity- Pegs

e) mid ocean ridges- The part of the paper that lifts up near thr crack between the tables.

f) the magnetic strips found in rocks parallel to the mid ocean ridges-

3.  Describe what you noticed about the height of the paper as it emerged from the gap compared to the paper futher out.

The paper was higher in the middle near the crack between the tables and it went down as the paper went further out,

4. Identify which of the strips you coloured would be the for the oldest rock and which the youngest rock.

The strip right th the ends of ech paper would be the pldest rocks and the ones near the centre would be the new rocks.

5. Identify which of these strips would be the first to be swallowed by an ocean trench.

The oldest ones which were the ones furthest out would be the first to be swallowed by a trench.

Prac 2- Colliding Plates

1. Compare th above tests with plate tectonics.

These tests correspond with collision boundaries and scraping boundaries. Collision boundariesare where one plate collides with another. These are destructive boundaries since rock is melted here and is returned to the mantle for recycling. Scraping boundaries are where plates scrape along eachother. They are conservative boundaries since they conserve rock. They do not create or destroy it.

2. The stack of paper had obvious layers. Assess whether rock has layers, and of so explain why.

Rocks do have layers.

3. State which tests simulated the following collisions.

a) a continental plate with another continental plate- Test 1

b) an oceanic with another oceanic plate- Test 2

c) An oceanic plate with a continental plate- Test 3

4. Identify a place on earth where each of these collision types occur.

Places where these collision types occur are called fault lines.

Basically, the bible. It gives us direction and guides us through our life.

• Do you ever compare images/values presented by the media to those of the bible? If so why? If not why not?

It depends on what they are presenting.

• Has this project challenged you to examine your values? Why / Why not

Not really, because I dont think that a school project like this would challenge me to examine my values.

When there is a high concentration of particles in the atmosphere that are slightly larger than air molecules (like smoke, dust, and pollutants), shorter and intermediate wavelengths of light (violet, blue and yellow) are scattered away. Therefore, only the longer wavelengths (orange and red) reach the observer’s eyes, giving the sun a orange-red appearance.

1. Describe what happens inside water droplets to cause a rainbow and explain how you can tell whether a rainbow is a primary or secondary.

Small droplets of water behave like tiny prisms in the sky. Sometimes the colours will reach our eyes after refracting snd undergoing total internal reflection. A primary rainbow is a band in the sky with red at the top and blue at the bottom. Sometimes a less intense secondary rainbow can be seen above a primary one. Light reahces our eyes from a secondary rainbow after two internal reflections inside each rindrop. This has the effect of reversing the colours so the bottom band is red.

The Elizabethan Era is the period associated with Queen Elizabeth I’s reign (1558–1603) and is often considered to be the golden age in English History.  It was the height of the English Renaiisance and saw the flowering of English poetryand literature. This was also the time during which Elizabethan theatre flourished and William Shakespeare and many others, composed plays that broke free of England’s past style of plays and theatre. It was an age of exploration and expansion abroad, while back at home, the Protestant Reformation became the national mindset of all the people.

Long-sightedness:  The exact cause of long sightedness is unknown and not well understood.

Short-sightedness: Short-Sightedness usually develops in children or young teenagers. You are more likely to develop it if it runs in your family.

b. the symptoms displayed?

Long-sightedness: Long-sightedness can cause blurred vision, headaches and tired eyes.

Short-sightedness: Short-sightedness causes distant objects to appear blurry and unfocused, while nearby objects remain in focus.

c. propose what sort of lens may be used to correct each vision.

Long-sightedness: Convex lenses are used to treat long sightedness, which are specially designed to bend the light so the retina can focus. These lenses are thinner at the edge than in the centre.

Short-sightedness: Concave lenses are used to treat short-sightedness. These are thinner in the middle.

a.     describe how optical fibre may be used in medical applications

Optical fibres are used in endoscopes. These flexible tubes contain optical fibres and can be passed via the mouth into the digestive system to provide doctors with images of the stomach and intestinal lining.

b.     identify the traditional medical techniques that optical fibres might replace

Cutting open the intestines and stomach.

c.     Evaluate the benefits of fibre optic technology to medicine 

Some tumours that would otherwise be impossible to treat may be destroyed by laser light sent down an optic fibre cable inserted nearby.

With social justice issues, I believe that the media give some facts, but not the full story. I think the stories are often one sided and they may sound very true but not all the facts are there.

Has it been difficult to find articles on social justice issues why/why not?

No, actually it hasn’t been very hard to find articles on social justice issues because it is such a big thing in today’s society.

Do you think that the media operates from a moral framework? Give evidence by using your research.

I believe that the media aren’t always completely honest, but they do try to get a message across that may help many people, so i think they work around a moral framework.

A critique is an analysis of a piece of work. It involves four main parts:

2. Outline the FOUR stages in a critique.

·         An introduction (which directs the reader’s attention to the publication and your response to it)

·         A summary of the article

·         Your analysis or critical commentary on the original text

·         Your evaluation or conclusion

 

3. Can a critique be positive? Discuss.

A critique can be both positive and negative. You can maintain a critical eye, without being mean, harsh or rude.

4. Critique the accuracy of the following articles:

1. Name the issue

Unfair workplaces

2. Describe one media account of this issue

Nike is a company that manufactures footwear and other sporting goods. It has its headquarters in the US but itts factories are located in other countries. The Nike Corporation does not actually make shoes. It designs and markets them. The manufacturing is contracted out to suppliers in Asia ( such as Vietnam, Thailand and Indonesia). The workers are paid very low wages and work in relatively poor conditions- often referred to as sweatshops.

3. Where did you get this media account from?

My old geography book

4. Is this media account correct or reliable? Why?

I believe it is reliable because if it wasnt i dont think they would teach it to millions of students.

A football article.
